LESSON 2

Cell Structure

Slide 2

Chloroplasts

Chloroplasts

Green organelles that make food

found only in plant cells

Slide 3

Chlorophyll

Chlorophyll

A green pigment that gives leaves & stems their color

Captures sunlight energy that is used to produce food called glucose

Glucose is a type of sugar

Slide 4

Mitochondria

Mitochondria

Organelles that release energy from food

This energy is released by breaking down food into carbon dioxide

AKA the powerhouse b/c they release energy from food

Some muscle cells have 20,000 mitochondria

Slide 5

Ribosomes

Ribosomes

Make proteins

Float freely or attached to the endoplasmic reticulum (ER)

Ribosomes are made in the nucleolus

Slide 6

Endoplasmic Reticulum

Endoplasmic Reticulum

A series of folded membranes that move materials (proteins) around in a cell

like a conveyor belt

Smooth ER – ribosomes not attached to ER

Rough ER – ribosomes attached to ER

Slide 7

Golgi Bodies (Gawl Jee)

Golgi Bodies (Gawl Jee)

Stacked flattened membranes

Sort and package proteins

Slide 8

Vacuoles

Vacuoles

Temporary storage spaces

Store food, water, waste

Slide 9

Lysosomes (Li Suh Sohmz)

Lysosomes (Li Suh Sohmz)

The word "lysosome" is Latin for "kill body."

The purpose of the lysosome is to digest things. They might be used to digest food or break down the cell when it dies.

Break down food molecules, cell wastes & worn out cell parts

Slide 10

From Cell To Organism

Tissue

Group of cells working together

Organ

Group of tissues working together

Organism

Any living thing made of 1 or more cells

Organ System

Group of organs working together
